What is Schizophrenia?
Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality. Although schizophrenia is not as common as other mental disorders, the symptoms can be very disabling. Schizophrenia involves a range of problems with thinking (cognition), behavior, and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations, or disorganized speech, and reflect an impaired ability to function. The disorder typically manifests in early adulthood.
Common Symptoms
Symptoms of schizophrenia fall into three main categories: positive, negative, and cognitive symptoms.
- Positive symptoms (psychotic behaviors not seen in healthy people): Hallucinations (seeing, hearing, or feeling things that don't exist), delusions (false beliefs not based in reality), thought disorders (unusual or dysfunctional ways of thinking), movement disorders (agitated body movements)
- Negative symptoms (disruption to normal emotions and behaviors): Reduced expression of emotions via facial expressions or voice tone, reduced feelings of pleasure in everyday life, difficulty beginning and sustaining activities, reduced speaking
- Cognitive symptoms (problems with attention, concentration, and memory): Trouble focusing or paying attention, problems with 'working memory' (using information immediately after learning it), poor executive functioning (understanding information and using it to make decisions)
- Early warning signs may include: social withdrawal, decreased performance in work or school, deterioration of personal hygiene, lack of emotion, unusual speech patterns, lack of motivation, insomnia or oversleeping
- Symptoms typically emerge in men in their late teens to early 20s, and in women in their late 20s to early 30s
Causes and Risk Factors
The exact cause of schizophrenia is not known, but research suggests that a combination of genetic, biological, and environmental factors contributes to its development. Risk factors include a family history of schizophrenia, exposure to viruses or malnutrition before birth, and psychosocial factors such as stressful life events or trauma. The condition appears to involve changes in brain chemistry and structure, particularly related to the neurotransmitters dopamine and glutamate.
Common Treatment Approaches
Schizophrenia requires lifelong treatment, even when symptoms have subsided. Treatment is focused on managing symptoms and typically includes a combination of medication, psychotherapy, and coordinated specialty care services.
Therapy Options
While medications are the cornerstone of schizophrenia treatment, psychotherapy can help manage the condition. Individual therapy can help develop coping skills, address daily challenges, and identify early warning signs of relapse. Cognitive Behavioral Therapy (CBT) for psychosis can help manage persistent symptoms and test the reality of thoughts and perceptions. Family therapy can improve family dynamics and support recovery. Social skills training, vocational rehabilitation, and supported employment can help improve functioning in daily life.
Medication Options
Antipsychotic medications are the foundation of schizophrenia treatment. These medications help manage symptoms by affecting dopamine levels in the brain. First-generation (typical) antipsychotics include haloperidol and chlorpromazine. Second-generation (atypical) antipsychotics include clozapine, risperidone, olanzapine, and others. In some cases, long-acting injectable antipsychotics may be used. Other medications, such as antidepressants or anti-anxiety medications, may be prescribed to treat other symptoms or co-occurring conditions.
Self-Care Strategies
In addition to professional treatment, self-care strategies can help manage schizophrenia:
- Take medications as prescribed, even when feeling well
- Attend all therapy and medical appointments
- Learn about the condition to recognize early warning signs of relapse
- Develop a daily routine and stick to it
- Avoid alcohol and recreational drugs, which can worsen symptoms and interfere with medications
- Maintain a healthy lifestyle with regular exercise, a balanced diet, and adequate sleep
- Build a strong support network of friends, family, and healthcare providers
- Join a support group for people with schizophrenia or their families
- Manage stress through relaxation techniques or mindfulness practices
- Set realistic goals and work toward them gradually
When to Seek Professional Help
If you or someone you know is experiencing symptoms of schizophrenia, it's important to seek help from a mental health professional as soon as possible. Early intervention can significantly improve outcomes. If someone is in immediate danger of harming themselves or others, call 911 or go to the nearest emergency room. With proper treatment and support, many people with schizophrenia can manage their symptoms and lead fulfilling lives.
